CD19FD431GO3F Equivalent and Substitute Parts

Part Overview

The CD19FD431GO3F is a 430 pF mica capacitor rated for 500 V with ±2% tolerance, manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general-purpose applications requiring high stability and reliability in through-hole radial configurations. Alternative part sourcing becomes necessary due to inventory availability, regional supply constraints, or specific compliance requirements such as RoHS certification levels or REACH regulatory status across different manufacturing regions.

Key Parameters

Substitute Part Grouping Explanation

The CM06FD431GO3 is identified as a parametric equivalent to the CD19FD431GO3F based on matching electrical specifications. Both components share identical capacitance (430 pF), tolerance (±2%), rated voltage (500 V), and dielectric material (mica). The mechanical parameters are equivalent, including lead spacing (0.343" / 8.70 mm), physical dimensions, and mounting configuration (through-hole radial). Both components maintain the same operating temperature range (-55°C to 125°C) and are classified as general-purpose applications.

Substitution validity is determined by these key parameters:

• Capacitance value and tolerance
• Voltage rating
• Dielectric type and stability
• Mechanical form factor and lead spacing
• Operating temperature range

Differences in RoHS compliance status and REACH regulatory classification do not affect functional equivalency but influence suitability for specific regulatory environments and supply chain requirements.

Parameter Comparison

Engineering Selection Recommendations

The CD19FD431GO3F is the preferred selection for applications requiring RoHS3 compliance and REACH Unaffected regulatory status. This part is suitable for European markets and industries with strict environmental compliance mandates.

The CM06FD431GO3 is functionally equivalent and may be selected for applications where RoHS compliance is not required and REACH-affected status is acceptable. Both components are Active status products from the same manufacturer, ensuring continued design support and availability.

Selection between these two parts should be based on the specific regulatory and compliance requirements of the target application and geographic market, not on electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can CM06FD431GO3 directly replace CD19FD431GO3F in a circuit?

A: Yes, from an electrical and mechanical standpoint. Both components provide identical capacitance (430 pF), tolerance (±2%), voltage rating (500 V), and physical configuration. The decision to substitute should be based on compliance requirements and supply availability rather than functional capability.

Q: What is the significance of the RoHS and REACH differences between these parts?

A: RoHS3 compliance indicates the CD19FD431GO3F meets European Restriction of Hazardous Substances regulations. The CM06FD431GO3 is RoHS non-compliant and REACH Affected, meaning it may contain restricted substances. Applications destined for European Union markets or requiring RoHS certification should specify the CD19FD431GO3F.

Q: Are the physical dimensions and mounting configurations identical?

A: Yes. Both parts share identical dimensions (0.642" L x 0.201" W, 16.30 mm x 5.10 mm), lead spacing (0.343" / 8.70 mm), maximum seated height (0.512" / 13.00 mm), and radial through-hole mounting type. Both are direct mechanical substitutes.

Q: What temperature range do these capacitors support?

A: Both the CD19FD431GO3F and CM06FD431GO3 operate across the same temperature range: -55°C to 125°C. This range applies equally to both substitutes.

Q: How does tolerance affect part selection?

A: Both parts carry ±2% tolerance on the 430 pF capacitance value. This symmetrical tolerance specification is identical across both substitutes and should not influence the selection decision between these two alternatives.
